DetailsWhen loading a saved Brickmania game, the game is loaded corrupted. Please see screenshot attached to see for yourself. There is one brick in the right side which is shown corrupted, and one corrupted rectangle in the left side of the screen which drops like a power object, and stays at the bottom of the screen.
This issue happens on Cowon D2 target. It doesn't happen on the D2's simulator. Looking at the code and comparing the loading/saving function against the Bubble's game functions, I can see that the return value of file operations is not checked (I'll fix that). In Bubbles, there's a single file operation of reading/writing the game context struct. In Brickmania there are several consequent file operation to read/write each variable. Maybe the drivers doesn't handle this well on this target. A workaround for that could possibly be to join all saved variables under one game context struct as in Bubbles, but that could mask a real bug somewhere else.

This task depends upon
Did a recent commit broke this or it just went unoticed to now ?
Sansa Fuze seems to successfully save and load game state.
Did a recent commit broke this or it just went unnoticed to now?
I've seen this in a while. It never worked for me, but I didn't follow brickmania from the beginning of it.
One possibility for this bug is that consequent rb->write() calls don't work as expected. I am clueless as to the cause of this bug.
